Problems with VNCServer console and Citrix Xenserver
Hope this is the right place... here goes.
Our college has Citrix XenCenter Enterprise and we have several RHEL ES 5.6 servers running now for various student and administrative functions. We know that XenCenter and the RHEL templates use vncserver as the root graphical console "0". We found, quite by accident, that we can also access the console "0" from an external VNC client with no password. This leaves us quite vulnerable. I've looked through all of the man pages and online to find a way to restrict access to console "0" from the local guest VM only and not from the world. I want to keep console "1" for use externally, though.
Does anyone have any ideas on now to accomplish this?
